Abstract
An evacuation station has a first chamber, a second chamber, and a dividing wall separating the first and second chambers. The dividing wall has a gap fluidly coupling the first and second chambers. The second chamber is fluidly coupled to a vacuum source. A package is made from a film and is arranged in the evacuation station. An inner volume of the package is in fluid communication with an inner volume of the second chamber via the open end. A control unit controls a pressure differential between a first internal pressure in the first chamber and a second internal pressure in the second chamber to cause aspiration of gas from the inner volume of the package.
